Favorite:
1. I love the lyric change for the movie adaptation of The Last Five Years where Jamie talks about Cathy being disappointed about "going again to Ohio" instead of "touring again for the summer." We've already seen how much Cathy hates the summer theatre in Ohio, and we know she'll be stuck there up until at least "See, I'm Smiling" - so it gives Cathy way more of a reason to be upset and vindicates her throughout this argument/song.
2. The playoff of "Alyssa Greene" from The Prom is cut from the album, and it leaves you in the mood of the scene much more effectively than the sorta-upbeat playoff. They even kept the album end for the movie adaptation.
3. The transition between "Ready, Set - Reprise" and "No Reason" on the Beetlejuice cast album is one of my favorite parts of the album! I understand why it's not in the musical, since there's a book scene in between, but it's so cool to listen to.
4. I do agree with the person who mentioned the SpongeBob album, but I do miss some of the lyrics from Chicago's "Chop to the Top" and I'm glad they were preserved somewhere. (Also, as someone who's a big fan of the band Lady A, Lilli and Ethan are really pulling double duty in that song by doing impressions of both the characters they're playing and also the lead singers of the band.)
5. On the Anastasia album, they turned "Still" into a standalone song without the short "A Rumor in St. Petersburg" reprise immediately before it, and I think the song is better for it - it becomes less about the chase that's about to ensue and more the inner struggles of Gleb's character.
6. I like the end of "You Will Still Be Mine" from Waitress better on the album than in the show proper. It gives the performer a button for the song and allows the audience to sit in the dramatic moment of the song. Also, it gave Nick Cordero a few more lines to sing on an album that did not feature him nearly enough, and for that I will forever be grateful.
7. The overture on the newest My Fair Lady cast album resolves into the final chord of "I Could Have Danced All Night," while the show itself transitioned immediately into the trumpets of the opening. I very much prefer the album's way of doing things, and I would love to know if this difference is a common thing within productions.
Now least-favorite:
1. I agree with the person who mentioned the string section leading into "It's Quiet Uptown" in Hamilton, and I also miss the "My Shot" playoff into "The Story of Tonight." It's so much fun, and otherwise, the next song seems to come out of nowhere.
2. There are maybe four measures missing from the lead-in to the "Seize the Day" dance break on the Newsies album, and it drives me a little bit up the wall every time I listen to it. Thank goodness for the proshot!
3. In the Broadway and licensed production of Matilda, there's a children's chorus that sings underneath the final chorus of "The Smell of Rebellion," and I really miss that when listening to the cast album.
4. I could speak at length about how weirdly inappropriate the fade-out of the Pippin finale into Theo's "Corner of the Sky" reprise is on the 2013 album. There are so many better ways to do that part of the song, and it cuts out Pippin and Catherine's a cappella singing in between, which is one of the best parts of the show.
5. I'm surprised nobody has mentioned the Spring Awakening cast album. Was it recorded and/or released before the show was frozen? I remember reading that the show changed some lyrics and added some harmonies, especially in "The Song of Purple Summer," right before previews ended, and I much prefer those versions of the songs.
6. Again, I agree with the person who mentioned the Chicago recording for SpongeBob, although I do think the three actors who left the production (especially Emmy Raver-Lampman) were still incredible performers and brought their own energy to their roles. The thing I miss the most is the end of "Bikini Bottom Day," which was expanded into an incredible finale to the song and provides the audience so much wonderful energy - and it has one of my favorite lines in the show, which is, "I will always vow and pledge allegiance to/This town that I hold dear/For all are welcome here."
